Not the same, but there are similarities. The most obvious difference is that Self is a dynamic language whereas Rust is statically typed. In the Rust bibliography (https://rustc-dev-guide.rust-lang.org/appendix/bibliography.html https://rustc-dev-guide.rust-lang.org/appendix/bibliography....) you find a link to http://scg.unibe.ch/archive/papers/Scha03aTraits.pdf http://scg.unibe.ch/archive/papers/Scha03aTraits.pdf which uses Smalltalk and also discusses the difference of their traits approach to Self. I guess they should also have added this reference: http://scg.unibe.ch/archive/papers/Nier05gTraitsCSharp.pdf http://scg.unibe.ch/archive/papers/Nier05gTraitsCSharp.pdf, which demonstrated in 2005 how to add traits to a strictly/statically typed language.
